Neuroinflammation, which is a hallmark of AD, contributes to disease pathogenesis and is inexorably linked with inappropriate microglial activation and neurodegeneration. We investigated sex-related differences in microglia in APP/PS1 mice and in post-mortem tissue from AD patients. Changes in genes that are indicative of microglial activation were preferentially increased in cells from female APP/PS1 mice and cells from males and females were morphological, metabolically and functionally distinct. Microglia from female APP/PS1 mice were glycolytic and less phagocytic and associated with increased amyloidosis whereas microglia from males were amoeboid and this was also the case in post-mortem tissue from male AD patients, where plaque load was reduced. We propose that the sex-related differences in microglia are likely to explain, at least in part, the sexual dimorphism in AD. 10.1038/s42003-021-02259-y 2399-3642 Communications Biology http://hdl.handle.net/10668/4035 34112929 http://hdl.handle.net/20.500.12105/18373 Microglial metabolism Sexual dimorphism Alzheimer’s disease Risk factors Amyloidosis Genes Microglía Metabolismo Características sexuales Enfermedad de Alzheimer Factores de riesgo Amiloidosis Microglial metabolism is a pivotal factor in sexual dimorphism in Alzheimer's disease
